Disclosed are a novel amino anthracene derivative and an organic electro-luminescence device using the same. More specifically, the disclosed amino anthracene derivative has a core (e.g., indenoanthracene core) of an anthracene moiety (with a high device characteristic) linked to a fluorene moiety (with a high fluorescence characteristic), in which in the core is substituted with at least one amine group represented by Formula 2 and the disclosed organic electro-luminescence device uses the amino anthracene derivative as a light emitting layer material so as to be enhanced in efficiency, operating voltage, and life span.

Photosensitizers with aggregation-induced emission (AIE PSs) were widely explored in photodynamic therapy. Numerous acceptors but few donors were reported to design AIE PSs. In this study, we developed a new kind of donor that can improve the comprehensive performance of AIE PSs by expanding the π extension of aromatic rings at the end of the triphenylamine group through acene enlargement. The absorption
This process is a process for production of a vinyl chloride polymer by suspension polymerization or emulsion polymerization of vinyl chloride monomer or a mixture of vinyl chloride monomer with a vinyl monomer copolymerizable with said vinyl chloride monomer in an aqueous medium, characterized in that the polymerization is carried out in a polymerizer, the inner wall surface and portions of the auxiliary equipment thereof which may come into contact with the monomer during polymerization being previously coated with a scaling preventive comprising at least one selected from dyes, pigments and aromatic or heterocyclic compounds having at least 5 conjugated π bonds, while controlling the chloride ion concentration in the reaction mixture to not higher than 100 ppm. According to said process, scaling onto the inner wall surface of a polymerizer, etc. during polymerization can be prevented effectively and surely.
